Product Description

Field of use of Promotion ZBL-P8100 Low Strain Pile Integrity Testing

  • The P8100 Foundation Pile Dynamic Detector is used to assess the integrity of concrete pile and identify the extent and location of the pile defect by using reflected wave method. 

  • It can be used for testing bored concrete pile and hammer pile and also for testing the structures with exposed top surface such as pillars.

  • The P8100 is provided with 2 channels of data acquisition and can acquire data from an accelerometer or an instrumented hammer or from two accelerometers.

Basic Principle of Promotion ZBL-P8100 Low Strain Pile Integrity Testing

         Hit the top of pile with testing hammer to produce stress wave, and the wave may reflect when it meets defect (pile bottom, crack, or soil middle layer) while it run downward through the concrete. The probe placed on the top of the pile receives the reflected signal. The instrument digitally processes the signal in order to judge the quality of foundation pile. According to the time interval between the arrival of the direct wave and first reflected wave, or time interval between the two continuous reflected waves, the depth of foundation pile can be determined by the following equation: D= VP×TP/2  (D - depth of foundation pile, VP – compression wave speed, TP- compression wave spread time)

Features of Promotion ZBL-P8100 Low Strain Pile Integrity Testing

  • Two-channel design can measure reflected wave speed accurately, and it can collect reflected wave at two places.

  • 1MHz high-speed data acquisition makes the minimum sampling time resolution reach 1us, providing more useful information and contributing to the discovery of shallow defects.

  • High Brightness and TFT colorful LCD screen.

  • Store waveform images for each tested pile.

  • New wavelet processing method can effectively judge the integrity of foundation pile in complex situation.

  • Water-proof; protection class reaches IP65.

  • Key and touch screen
